NASA PO.DAAC http://podaac.jpl.nasa.gov/
The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is NASA’s data center responsible for data management and distribution of satellite oceanographic data, as well as providing support for its scientific user base. Its holdings consist of ocean surface topography, sea surface temperature, salinity, winds, ocean circulation, and gravity. PO.DAAC’s holdings for ocean surface topography consist of Seasat, GEOS-3, TOPEX/Poseidon and Jason-1, along with PI provided datasets for OSTM/Jason-2 and SARAL/AltiKa. For information on how to obtain data from PO.DAAC please visit the data access section.

NOAA NODC http://www.nodc.noaa.gov/
The National Oceanographic Data Center (NODC) is one of the national environmental data centers in NOAA. Its mission is to provide scientific stewardship of marine data and information. NODC provides near real-time and delayed-mode product distribution, archive services, and long-term data stewardship for the OSTM /Jason-2 and future Jason-3, and historical Geosat and GFO products. The archive strategy developed by NODC for archiving OSTM/Jason-2 and Jason-3 involves using NOAA Comprehensive Large Array-data Stewardship System (CLASS) to provide the information technology infrastructure to support ingestion, archival storage, and basic access to the Jason-2/3 data.

AVISO is the data archive for altimetric missions and related datasets for the French space agency, CNES. AVISO holds data for the altimetric missions ERS-1, TOPEX/Poseidon, ERS-2, Envisat, Jason-1, OSTM/Jason-2 and SARAL/AltiKa. Their uniform space-time gridded sea level anomaly datasets combining data from several satellites are widely used.
EUMETSAT is the European Union meteorological satellite agency. Its focus is on operational satellites that can provide data for weather, climate and environmental studies/applications. It houses near real time data from OSTM/Jason-2.
Non-Mission Mandated Centers
The Radar Altimeter Database System (RADS) provides along-track altimeter data with the most up-to-date corrections, in text file format, with user-selected correction algorithms, as well as software to handle the database and extract data at a user's computer. RADS is an independent data distributor.
